ACT telescope is located inside of the micro-wave shield seen here at 5140 meters above the sea-level in site on Cerro Toco, in Northern Chile.Receiver positioning scheme on the telescope optical axis inside the cabin.  Neutral cabin floor position is tilted down at 5 percent to horizon, bringing both pulse tube-tubes to vertical positions.Receiver cross-section, showing preliminary design with two of three optic tubesJDry-100-ACTPol in its test enclosure, attached to the automated Gas Handling System GHS4, during its test at Janis.The Receiver during final tests at University of Pennsylvania test facility before shipping to Chile, fully assembled and with electronics attached.  Three optical inputs are seen, one with Teflon window exposed.

JDry-100-ACTPol Cryogen Free Dilution Refrigerator for the Atacama Cosmology Telescope (ACT)
Janis Research’s ultra low temperature (ULT) group is proud to announce that it has developed, in collaboration with multi-agency scientific collaboration team called ACTPol, a new pulse-tube cooled cryogenic platform for the Atacama Cosmology Telescope (ACT). The ACT is a six-meter Gregorian telescope located at an altitude of 5,200 meters (17,000 ft) on Cerro Toco, in Northern Chile, and is dedicated to studies of the structure and evolution of the early universe through direct observation of the Cosmic Microwave Background (CMB) radiation at different polarizations and with arcminute resolution.
